Description
Technical field
The present invention relates to glucose preparing technical field, more particularly to a kind of cassava whole-powder direct method method for manufacturing sugar.
Background technology
Domestic amino acid（Particularly glutamic acid）Fermentation industry is all to use corn to supply fermenting and producing for sugaring raw material, and expense is very big.Because corn involves China's grain security major issue and the problems such as price goes up year by year, make that industry is in meagre profit or loss is managed.Our company proposes to use tapioca slice（Quan Fen）Direct method Closed Circulation in Sugar Production technique, is used for amino acid fermentation industry.
Tapioca slice is crushed, after soaking processing, without obtaining through refining starch process process, directly using the technique of two enzymes method glucose, be called direct method technique.Because cassava materials have the characteristics that, direct method technique is set to be produced used in starch sugar（Particularly it is used for fermentation industry）, to reduction production cost, reducing construction investment has great benefit.
1st, tapioca slice（In terms of air-drying, similarly hereinafter）Composition：Moisture 14%；Starch >=72%；Protein 2.6%；Fat 0.8%；Fiber point 3.3%；Ash content 2.4%.
2nd, starch-containing height, and, silty is fine and smooth containing protein, pectin, fat seldom, gelatinization point is than relatively low.
3rd, color is shallower, decolourizes to be easier.
4th, it is less containing reduced sugar, comparatively it is difficult corruption.
5th, above feature is highly beneficial to tapioca slice direct method technique, because：
When a, glucose processed, protein, pectin and fat are very big on saccharification and influence of decolourizing, and because the enzyme system used in production is impure, contain a small amount of protease, pectase and lipase, these enzyme decomposing proteins are amino acid, make pectin dissolution, lipolysis, these catabolites are solubility, it is difficult to remove, during heating, and coloring matter easily is formed with glucose, and filtration difficulty can be caused again.Pectin is almost nil with fat content in tapioca slice, and protein is also seldom.This is just brought great convenience conveniently to direct method technique, and sugared quality is also improved.
B, tapioca root are starch-containing very high, it is impure few, and it is relatively finer and smoother, gelatinization point is low, the difficult gelatinization not as cornstarch, therefore very high temperature and pressure are not required in production, it is fewer than other starch containing amylose, containing about 17%, easily decomposed by acid or enzyme, impurity dissolution changes also less with color and luster, is easier during decolouring.
C, due in tapioca slice containing reduced sugar it is less, when being soaked after crushing, both do not resulted in starch dissolution loss, be not easy to fermentation corruption.
6th, during the direct legal system glucose of tapioca slice, the composition of the useless potato slag of filtering changes very greatly with process conditions, and approximate composition is as follows：Protein 4-5%；Residual sugar 20-30%（This sugar as far as possible is washed with clear water to the greatest extent, wash water can reuse be used as to size mixing before liquefying）；Crude fibre 20-25%；Other 12-20%.Tapioca slice per ton can obtain 150-180 kilograms of dry potato slags in production, and moisture content is different regarding process equipment.This potato slag must be mixed with the higher material containing protein to be made feed or fermented is directly prepared into biological feedstuff.
Compared with maize raw material, one is to obtain through refining process without starch directly to refine sugar, and technological process is simple；Reduce substantial amounts of human and material resources, power and operating cost；Two be direct method technique, can reduce the plant and equipment of starch process processed, greatly reduce fund input；Three be the recovery rate for improving starch sugaring, reduces production cost；Four be enterprise's many a kind of raw material selections, Duo Yitiao roads.

Embodiment
Further supplement, but do not limit the invention in any way are done to the present invention with reference to specific embodiment.
1st, except iron impurity elimination：Most common impurity has sandy soil, cellulosic in tapioca slice raw material（Skin）And metal impurities, it is necessary to thoroughly cleaning is carried out to tapioca slice, is the basic process of process glucose quality after ensureing.Meanwhile, the part hydrocyanic acid in root tuber can also be removed in cleaning process.Equipment uses the drag conveyor and drum washing machine carried except magnetic device.
2nd, wet pulverizing：Crushed using water and raw material by together with entering pulverizer（20-30 mesh）, the advantage of this method is that material powder will not be flown upward.Both the loss of raw material can be reduced, work situation can be improved again, a whole set of cleaner can be also saved.But have the disadvantage that the slurry crushed can only be immediately available for production, should not store.Size-reduced be made after slurry enters steeping tank.Equipment uses beater grinder.
3rd, slurry is soaked：The quality of quality is soaked, it is very big to whole technogenic influence, because using coarse raw materials using direct method sugaring（Without obtaining through refining starch）.It is first of refining step to soak process, can dispose most of pigment, soluble protein and hydrocyanic acid in coarse raw materials with when arranging soaking water.If these impurity enter liquefier, liquefier quality and later process product quality are largely effected on, increases production cost.Such as soak process and reach technological requirement, the color and luster of slurry can be substantially reduced, liquefier color and luster can close to commodity starch liquefier level.Vacuum suction filter separation water in road after slurry is added by a certain percentage when being pumped into steeping tank, charging is finished, and is continued after stirring, and is soaked about 1 hour or so, and upper strata soaking water is discharged into sewage disposal process by sedimentation.Secondary immersion about 1 hour or so is then carried out with seperator separation water, i.e., is separated from water slurry with vacuum suction filter（This water is pumped into secondary immersion and used）, and clear water spray washing is used, make soluble impurity in slurry（Including hydrocyanic acid）Remove as far as possible, then pump goes to size mixing, liquefied.Equipment uses carbon steel tank and vacuum suction filter.
4th, size mixing liquefaction：General concentration of sizing mixing is equivalent to starch slurry 12-18 Baumes, and PH6.0-6.2 adds Thermostable α-Amylase, with being pumped into water heater（Injector）Paste（Liquefaction）Change, and maintain certain time, and after cool through flash tank, be depressured into laminar flow tank insulation maintenance 60-100 minutes.Equipment uses injector or water heater, laminar flow tank.
5th, filtering is slagged tap：Liquefaction end is pumped into automatic plate frame press filter and carries out deslagging filtering.Liquefier is pumped into saccharifying tank and is saccharified.Equipment uses full automatic plate frame filter press.
6th, saccharification is decolourized：Liquefier adjusts PH4.2-4.4 with hydrochloric acid, and 60 ± 1 °C of saccharification temperature adds compounded saccharifying enzyme（0.5% pure glucose can be improved, without the enzyme that goes out.Not only operation but also steam saving are simplified）It is saccharified.Saccharification terminates to use absolute alcohol titration to check without muddiness as terminal.Then PH4.8-5.0, direct pump people Filter Press are adjusted with alkali.Now sugar concentration 22-28Bx, stores up sugar bowl to be concentrated with pump people.Equipment uses carbon steel tank and full automatic plate frame filter press.
7th, it is concentrated by evaporation：Concentration is for fermentation flow sugaring needed for liquid glucose is concentrated into.Equipment uses MVR evaporators.
The process system uses direct method technique, can avoid the loss caused during cassava starch in company with the separation of potato slag.Because in cassava, having 50-60% starch to belong to free starch, in starch processed, one by broken, is easier separate out.And separately have that 40% or so starch is wrapped in the fibre bundle of cassava or cassava is subcutaneous, it is difficult to separate with the method for being generally separated.Starch is caused to abandon and lose with slag, yield declines.And direct method technique is used, whole materials all enter liquefaction process, and by hydrolysis of the amylase to starch, the starch in fibre bundle or cassava skin is liquefied together, water is dissolved in and extracts, and recovery rate is improved.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for those skilled in the art, the present invention there can be various modifications and variations.Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection.
